The invention provides a motor torque control method and device, electronic equipment and a vehicle, belongs to the technical field of vehicles, and aims to determine a safe direction judgment rotating speed with increased rotating speed redundancy as a standard for positive and negative direction judgment of a motor rotating speed, so that the torque reversing difficulty is improved, and the frequent reversing of the torque is avoided. And when the torque control risk exists, active zero clearing processing is carried out on the current request torque according to the preset torque change rate, the torque change amplitude when the torque is reversed is reduced through the active zero clearing processing, and the degree of rotating speed fluctuation generated when the rotating speed direction changes is reduced, so that the pause feeling is weakened. By adding control means of rotating speed redundancy and active zero clearing processing, under the condition that the rotating speed of the motor is influenced by braking force interference and changes in positive and negative directions, fluctuation of the rotating speed of the motor is not aggravated due to reverse torque reversing processing, so that the problem of continuous jerking of the motor is avoided, and the driving feeling is improved.

    本申请提供一种电机扭矩的控制方法、装置、电子设备及车辆,属于车辆技术领域,将增加转速冗余量的安全方向判定转速确定为电机转速正负方向判定的标准,提高了扭矩换向置反的难度,以避免扭矩的频繁换向。并在存在扭矩控制风险时,根据预设的扭矩变化率对当前请求扭矩进行主动清零处理,通过主动清零处理来降低扭矩置反时的扭矩变化幅度,并降低转速方向变化时产生的转速波动的程度,以减弱顿挫感。通过增设转速冗余量和主动清零处理的控制手段,在电机转速受到制动力干预影响,发生正负方向变化的情况下,使电机不会因为扭矩换向置反的处理加剧电机转速波动,从而避免电机连续顿挫的问题,提高驾乘感受。
